To all whom it may concern: I

Be it known that LERAs'rUs E5WINKLEY, a citizen of the United States,residing at Lynn, in the county ofjEsseX andstateof lvlassachusetts,have invented [certainlm provements in Heel-Building Machines, of whichthe following description, in cennecspecifioation, likereferen'cejcharacters on the drawings indicatin'glike parts in theseveral figures. f This invention relates to heel building machines, andmore particularly to that type of heel building machine whereby aplurality of lifts or pieces ofleather, or other material, are fastenedtogether toform a heel.

Heretofore it has been the common practice to, build heelsby ,manuallyassembling a number of lifts,gone on top of the other, in a mold, andfastening them together by one or more fasteningsor-nails driven. intothe pile of lifts while under pressure. In the operation of heelbuilding,.the height of the resultant heel has depended upon the skilland care of the machine'attendant in placing the required number oflifts of properthickness in the mold, and, as a result, heels of aseries have not beenuniform.

Lack of uniformity in theheight ofsuccessive heels in a run of heels,and the 0bjections thereto, may manifest themselves not only after theheels are attached to the boots or shoes, but'also during the treatmentto which the built up heels are subjected after or before leaving theheel building machine. For instance, the heel lifts have'their contactsurfaces provided with' an adhesive or glue, and in order that thecontour edges of the lifts may be held in closeconta'ct when the heel isfinished, the built up heel is placed in a heel press where the heelis'subjected to pressure foratiine sufiiciently.

long to enable the glue or adhesive to. set or becomedry. If, however,the heels built in the heel building machine are not ofthe properheight, or too low, the fastenings or nails which secure the liftstogether, may

not be driven completely into the pile of lifts, and such projectingnails will not permit the heel liftstoireceive the desired uniformpressure of the clamps when in the heel press. This may result ineracks'appearing between the heel lifts when at.-.

tached to the boot or shoefland finished, or worn. 1

I EEL-BUILDING Macrame.i

1919. Serial no. 311,968.

Attempts hai e been made to: overcome this "objectionable" variation inthe height of built-up heels produced in the heel-building machine, bythe use of gage plates arranged in'pil'es about the support for the heellifts,

so, thatftlie mac'hine' attendant could feel the gage plates withonehand, and with the other hand select thelift or'liftsof the properthickness tobring the heel up to the desired height. In this, as in theolder method however, the care andskill of the machineattendantfdeterininesthe height of thefpile of lifts, and, consequently,variationsin the heights of the heels result.

more satisfactory solution of the "prob:- lem, however, is furnished bythe machine of "the" United States patentlto John R. Richardson No.1,148,716, dated August 3, 1915, wherein automatic inean's is providedfor measuring the height of thepileof heels assembled for. treatment inthe heel builder,

In this machine a measuring means actsto e'ineasure' the pile of liftsbefore they are put under pressure, and if the pile is not inaccordancew th a" predetermlned standard,

operation fof the securing means is" pre vented, and the'attendantmayfcorrect the inaccur'2;cy. This-has resulted in a reater uniforniityvin the height of a run'o built-' up heels,'and issatisfact0 ry andefficient in operation. It is desirable, however, that the height .of'the finally completed: or, compressed ,pile of heel lifts may b euniform, and not that the 'fastenings' of nails be not driven intoth'epileof lifts 'to secure them together. The material of the lifts, forinstance, may not always'be uniform in characte'ijso that whilesuccessive pilesof heel hits-may .n'ieasure the same height before they,21'6 subjected;,topressure, they may vary inheight after "compression.An important feature" of thepresent in VClliilOl],.tl'l6l6lO l, consistsofmeans for pre- Venting'the operation [of the securing means a when apile of heelj liifts under compression does notconform'toapredeterinined standard. The consequence ofthis'is that'whenthe machine is adjusted for building heels of a certain height andsecuring the lifts together' only' whenthe pile of compressed liftscorrespondsto a predetermined height,

successive 'heels treated by the machine will beef substantially" the'same height. v l vhenthe heel lifts are placed'i'n' the heeL buildingmachine, they are usually positioned relative to the front of themachine by the heel breast which bears against a breast gage or finger.Some machine attendants prefer to have the heel breast facing towardsthe rear of the machine or away from them, others. prefer that the heelbreast be facing towards the side of the machine, and still othersprefer it facing the front. Thesevarious preferences are incidental toindividual characteristics which enable the attendant to place the heellifts in position for treatment with greater facility when the breastofthe heel faces in some particular direction. 2

Another important feature of the present invention, therefore, consistsin providing a lift support which may be adjusted into different liftassembling positions to place the breast gage so that it shall face indifferent directions relative' to the front of the machine. This featureof the invention may be variously contrived,but in the presthe operatingparts of the machine and cause improper operation and wear or breakageof parts. Another important feature of the invention, therefore,consists of providing a. receptacle beneath the heel lift support andsurrounding the fastening inserting, or driver, mechanism for catchingthe adhesive or glue expressed from the lifts when subjected topressure,in combination with a deflector to deflect the adhesive or glueaway from the operating parts into the receptacle.

The invention further consists in certain features of construction andnovel combinations of parts, which will be hereinafter described in thespecification and in addition to the above, pointed out in the claims.

In the drawings:

The glue thus discharged illustrated as a convenient means forexplanation of the invention and its cooperative relation with parts ofthe machine.

The supporting frame may be of any usual character suitable forsustaining the operating parts and as shown comprises a base portion 1from which rises the column 2 provided with bearings 3,4, in which ismounted thereciproca-ting rod 5 constituting part of thefastener-inserting or naildriving mechanism. The rod 5 hassecured to ita lug 6 to which is pivotally connected at 7, 7, the rods 8, the lowerends of which are connected at 9, 9, with an arm 10 ofa bell crank leverpirotally mounted on the machine frame at 11. The other arm 12 of thebell crank or rocking lever is connected by a link 13 to an arm 14secured to a rock shaft 15,,mounted in the lower part of the machineframe and having secured thereto the treaidle 16,. the constructionbeing such that by depression of the treadle 16 the rod 5, heretoforedescribed, will be moved upwardly for inserting the fastening, ordriving the nail or nails.

The' column 2 supports at its upper portion a head 17 to which .isbolted at 18 the bent arm 19 which constitutes the support for the upperpresser member, as will more fully appear.

.i-rbove the head 17 is secured the receptacle 20 provided with abearing portion 21 through wiich the upper extension of the rod 5passes. The bearing portion 21 which may be connected to the receptacle20 in a. manner to provide an adhesive or glue containing portion 22,extends some distance above the bottom or lower portion 23 of thereceptacle 2!), the construction being such that any adhesive gluedropping from the'heel or running therefrom during thecompressionthereof, may drop within the receptacle 20 and be sustained in the space22 without danger of coming in contact with theoperatin parts of themachine, and more particulafly the reciprocating rod 5.

The upper end portion of the receptacle 20 serves to support a plate241- which may constitute .a form of table. The support at may beconnected to the top of the receptacle 20 by the flanges 25, andsuitable securing means may be provided for holding the support 24 andreceptacle 20 in associated relation. I

The support 24 has a hub portion 26 in whichv is mounted a nail block27, the upper end portion of which, is provided with a flange 28 whichrests upon the upper end of the hub portion 26 and may there-be securedin fixed position. The nail block 27 is provided with a passage way orpassage,

which extends upwardly from: the driver head and enters the nail block,as indicated in Fig. 3. The cap '31 maybe secured to the driver head 30by appropriate means, such as the bolts'33. i i I Mounted upon the topof the support 24 is the lift support 34, Fig. 3, which,-in the presentinstance of the invention,is of general circular shape in plan andmounted for rotative movement. about the axis of the nail block. Aseries of holes or threaded openings formed in the support 24 atintervals, enables the lift support 34 to be rotated about the axis ofthe nail block 27 and secured in rotated oradjusted position by suitablemeans, such as the, bolt 36, Fig. 3. In the present instance of theinvention the lift support 34 has adjustably secured thereto the breastgage 37 and the side gages 38 which are secured in desired relation ofadjustment to accommodate the heel lifts which are to be securedtogether. The breastgage may be variously secured to the lift sup portand rotate with it, and in thep'resent instance, is shown asprovidedwith a'slot 39 in the lower foot portion of the gage throughwhich extends the bolt 40,'the construction being such that by looseningthe securing bolt 40 the breast gagemay be adjusted relatively to theside gages to accommodate the heel lifts which are to be treated; Theside gages 38, or fingers as they aresometnnes called, may also besecured to the lift support 34 adjustably, as by means of-the bolts 41,one of which is indicated in Fig. 3.

When the machine attendant desires to have the breast gage 37 inposition facingto the rear of the machine, he or she turns'the liftsupport 34 until the breast gage 37 "is in the desired location andthereupon secures the lift support 34 in position by means of thesecuring bolt 36. If, on 'the other hand, the machine attendant shouldde'sire the breast gage 37 to be located towardsthe front of themachine,,in order to facilitate r I r an extent to produce the desiredpressure the piling of the lifts uponthe lift support,

- stance, as a cap piece 47 threaded into the upx-is provided with, athreaded recess 49 in i which is adjustably "mounted the presser stem'50 carrying thepresser 51 ,Whicl1 con- :stitutes one of thepresser-members for-exerting-pressure upon the heel-lifts placed{between them. In order to prevent rotative I movement of the plunger 43as itis reciprocated in its-support, the lower end portion of;

- he-or she lunscrews the bolt 36, turns. the lift support 180 from? theposition indicated in I Fig; 3-, and a then; secures the parts in thenew position by means of the bolt 36.

, The arm 19, which 1 constitutes 2 one convenient meansi for.supporting: the upper presser member, is piovidedwith a hub portion 42,F 3, in which is mounted a plunger 43 having an enlarged head 44 between'avhichand'thelower end of the enlarged chamber in the hub, is thespring 46,

normally tending to lift the plunger 43. The head-44 on theplunger 43maybe held in, position by suitable means such, for inper end of theplunger and-affording a surface against which may act the presser cam48. a a cap 31 for securing thereto the driver 32,

I iThe'lower end portion of-the plunger 43 the plunger43 has securedthereto an "arm 52, carrying-a pin 53 which rides inasocket 54 as theplunger is re-ciprocated. Suitable means may be'provided for preventingrotative movementof the adjustingrstem 5 0 of the presser to preventdisturbance'of adjust Inent during reciprocation of the plunger.

Rising fromthe arm 19 are thesupports 55, best shown in Fig.2, betweenwhich is mounted the supporting" pin or shaft 56.

Mounted upon the supporting pin or shaft 5 6 is the pressercani'48jwhich' constitutes one convenient form of means for applying pressureto the heel lifts through the upper presser meniber, The presser cam 48has itspresser surface 57 adaptedto contact with the 'headorcap portion47 offthe plunger 43', the construction being such that tr'acloclrwise,view-ing 43will be depressed. t

Thepressure cam"48i1s provided with a 3, the plunger 'socketed or]recessed portion 58in which is mounted a spring 59, one end of I which,Y at 60, rests against the end wall of the socket'or recess anidftheother end 61 of which rests upon a lug 62 carried a segment portion 63of thecamactuating means, which, inthe present instance of the Iinvention, comprises 'a handle 64 and yoke 65 having a'hub op 1 10 uponrotative movement of the cam 48 coni upon the heel. lifts mounted on thelift support, and the pile of heel lifts has been compressed, it isdesirable that the height of the compressed pile of lifts may bemeasured, and if either too high or two low, that the fastening or nailbe not driven into the pile of lifts to secure them together.

Pivotally mounted at 66 on .the machine frame, or, as in the presentinstance, upon the arm 19, is the measuring lever 67, the lower end 68of whichengages a locking member which, under certain conditions, to behereinafter described, prevents operation of the heel liftsecuring meansor driver. In the present instance of the invention .the locking meansconsists of a slide 69 mounted for reciprocating movement in a bearing70 sustained upon the machine frame, and connected to the lower end ofthe measuring arm 67. The connection between the measuringxarm 67 andthe slide .69, in

the present instance, consists of a' slot 71,

formed in the .end of the slide 69 through which the end 68 of. themeasuringlever extends, the construction being such that should themeasuring lever, 67 be moved about its pivot 66, the slide 69 will bereciprocated- Mounted upon the rod 5, which, as heretofore explained,constitutes part of the operating mechanism of the securing means, is astop collar 72 which may be secured in desired position on the rod bymeans of a set screw 73, Fig. 4. The collar 72 has a flange 7 which,when the rod 5 is in its lowered or. inoperative position, is below theend of the slide 69, as indicated in Fig.1, so that the rod 5 cannot beraised when the slide 65 is extended inwardly over the flange 74, asindicated in Fig. 1, and, perforce, the

securing means or driver cannot be actuated. The presser cam 48 carriesa lug 75, Fig. 6, having a. beveled surface 76 which is adapted to beengaged by a reversely beveled surface 77 on a lug 78 extending from thesegment 63, the construction being such that the spring 59 normallymaintains the beveled surfaces 76 and 77 in contact.

The measuring lever 67 hereinbefore referred to, has an upwardlyextending arm 79provided with a roller or side extending pin 80 which isadapted to rest upon the contour or peripheral surfacesofthe lugs and 78when the partsare in closed or normal position. When the presser cam 48is in a position of pressureand the pile of compressed heel liftsconform to a predeterminedstandard,-the roll on the" measuring arm restsat the junction between the lugs 75 and 78, and as the cam actuatingmeans, in this instance the handle 64, is further turned, the lug 62 ismoved against the tension of the spring 59 while the presser cam 48remains fixed, the effect being that the lugs 75 and 78 areseparated andthe roll 80 may move inwardly under the impulse of the spring 7 9*, asindicated in Fig. 3, thereby withdrawing the slide 69 from above theflange 74 of the sleeve 7 2 and permitting operation of the securingmeans or driver. If, however, the pile of lifts is too 'highwhen thepresser cam 48 is actuated to lnlPillhPTGSSllIB thereto, the position ofthe lug 78, while separating from the lug 75, will be such as tointerrupt the inward movement of the roll 80 and, perforce, withdrawalof the slide 69 from its locking position'. The result is that under thecondi tions stated, the securing means or driver cannot be operated andthe fastening or nail will not be driven. On the other hand,

should the pile of heel lifts be too low, the

presser cam #18 will be moved farther than when the lifts are of theproper height, and will interject the projection 75 into the pathflofmovement of the roll 80, with the result that again the slide 69will remain in locking position and prevent operation of the securingmeans or driver. Thus it will be seen that the measuring means measuresor de-- termines the height of the pile of lifts while they are underpressure and if the pile of lifts be either too high or too low whenunder pressure, the measuring device will prevent operation of thesecuring means or driver.

lVhen the pile of compressed heel lifts conforms to the predeterminedstandard, and the measuring device therefore permits operation of thesecuring means or driver by inward movement of the roll 80, it isnecessary to 1no .'*e the roll 80 outwardly to restore themeasuringdevice to its normal position after the fastening or nail has. beendriven and when the presser cam is moved to its non-pressing position.To offset this the present invention provides the yoke 65 ,to which thehandle 64 is connected, with a setting cam 81 which, as the handle 6i is.IDOYGCl clockwise from the posit-ion. of Fig.

3 to that of Fig. 5, acts upon the roll 80 to move it outwardly, asindicated .in Fig. and past the tip end portion of a pawl 82 pivoted at83 to the segment 6?), whereupon a spring 8a actin on the pawl, snaps itback into its normal position with the end of the pawl resting againstthe cam 81, as indicated in Fig. lVhen the pawl has snapped hack intoposition against the cam 81, after the passage of the roll 80, thecontour surface of the pawl forms a traclt on which the roll 80 rides asthe presser cam is moved into presser position asindicated in Fig. 3.

Should the adhesive or glue which is expelled from between the heellifts while under pressure, find its way to the pressure sure againstsuch-interference, the rod 5,

within the receptacle 20, isfprovided with a deflector 85, Fig. 4:,which may be conveniently formed as part of the driver head 30, so thatshould any adhesive or glue drop downwardly into the receptacle 20 itwill be deflected outwardly from the rod 5 into the lower portion of thereceptacle where all danger of interference with the securing means ordriver is avoided i I WVhile the pre-sent'invention has specialadvantages in connection with a heel build ing machine of the generaltype herein described, it is not restricted thereto, but may be employedwith advantageous results in connection with other forms of heel building machine to produce compressed heels of uniforrh height throughoutthe series.
